LUBRICATIN G DEVICE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed February 6, 1919. Serial No. 275,302.

To all whom it may concern Be it known that I, GOTTLOB KLUMPP a citizen of Germany, having declared my 1ntention of becoming a citizen of the United States, and a resident of the boron h of Manhattan, city, county, and State 0 New York, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

My improvements relate to devices of the cup-funnel type used for holding and feeding a semi-fluid lubricant to journal bearings and the like; and the main object is to attain a satisfactory and perfect gravity feed, obviating the need of followers, forcing springs, etc.,such contrivances being more or less complicated, expensive, and objectionable for various practical reasons. Other objects are, to render visual at all times the presence or absence of an adequate quantity of the lubricant within the container and to effectually secure the parts in closed relationship in a simple manner. Hence, the invention-consists in the specific construction and arrangement of parts described and claimed,distinctive features being my avity feed stem, the visualizing means, an the securing and closing means, all as hereinafter fully set forth.

In the accompanying drawings,

gig. 13, is an inside view of the cup cover; an

Fi 14, is a view showing a m di ca i n of the cover spring.

The container for the lubricant (not shown) is essentially a funnel shaped cup C, the discharge passage 0, from which extends through the threaded nipple c, by means of which latter the container C, is attached to the capplate of a journal bearing, or the like, as indicated by dotted lines in Fi 3.

The upper portion of the container is preferably although not necessarily cylindrical in general configuration, and is formed with a plurality of sight apertures 0", preferably extending all the way to and through the top of the shell of the cup C, so as to form between said sight apertures 0", sections of side wall 6 which are more or less elastic and resilient at their upper portions,it being understood that the shell of the container C, is metallic.

My preferred form of lubricator has three of these elastic resilientsections c of side wall, equidistant, and consequently has three equidistant si ht apertures 0, between them, although I 0 not restrict myself in this respect, except to state that a plurality of both sight apertures c", and elastic resilient wall sections 0 is desirable. Each elastic resilient wall section 0 is formed, near its upper free edge, with an external knob or protuberance 0 made preferably by upsetting the metal outward, in a manner well known in the art. The flange 7c, of the cover K, is formed with coincidental internal recesses or sockets k, so that these protuberances c, on the elastic resilient wall sections 0 of the container C, and these cover sockets k, for the reception thereof, constitute practically snap fastenings to hold the cover K, in position. I thus attain not only .very simple and cheap, but very efi'ective means, for removably attaching the cover K, to the container C.

A little below the lower edge of the sight openings 0, I form the container 0, with an internal annular shoulder c, which constitutes the seat of a transparent lining G, preferably consisting of a cylinder of glass, which fits snugly upon its seat a, and within-the casing, the window sills c, overlap.- ping the joint between the lower edge of the cylinder (hand the casing, and hugglngthe cylinder with sufiicient tightness to prevent the exuding of lubricant over said sills a, as will be understood by reference to Fig.1 3. In this connection it may be stated t at when the cover K, is applied the upper portions of the elastic resilient sections 0, also fit the'cylinder G, snugly, but that they otherwise have suflicient play to admit of the snapping of the cover in place with its sockets In, fitting over the proturberances (2 on said elastic resilient wall sections of the container shell.

The cover K, is also formed on its inner side with a fiat spring 10*, which bears pcripherally, when the cover K, is positioned on the container (1, against the upper edge of the glass cylinder G, as shown more particularly in Figs. 3 and 5, of the accompanying drawings, thus not onl holding the glass cylinder G, firmly on its seat a, but also holding taut and firm the snap fastenings 0 and 7c, and preventing looseness or rattling of the parts involved. It is obvious that the flat spring instead of being in the form of a disk with a continuous annular periphery, might with like results be formed with a plurality of radial arms adapted to contact with the upper edge of the cylinder G, as for instance the modification of said spring 70 shown in Fig. 14.

F, is a gravity feed stem positioned centrally and loosely or freely within the container C, and extending at its lower extremity through the discharge passage 0, thereof so as to rest against a journal to be lubricated, as indicated more particularly in Fig. 2, in which the dotted circle J, re resents the cross section of a journal. he feed stem F, is preferably, althou h not necessarily, made of three wires f, f, f, of equal length, bound together by a wrapping of solder, lead, or alloy 7", and having their upper ends bent over laterally as related to the center of the stem to form equidistant radial arms 7*, f 7', which space and centralize the upper end of the feed stem with in, and as related to, the cylindrical part of the container C. By the use of a plurality of wires 1, f, f, in the formation of the feed stem in a convenient and cheap manner, provide it with a plurality of feed grooves f f, f, which, by aiding capillary attraction, facilitate the feed by gravity of the lubricant down the lower portion of the stem and through the discharge passage 0, of the container U, and to the parts to be lubricated. The wrapping f, not only unites itself with the wires f, f, f, integrally, but it also performs the function of a weight to hold the feed stem F, down to its work in the relatively thick, semi-fluid lubricant which is introduced into the container C, in which function the feed stem i supplemented by thevibration to which t e parts are subjected under ordinary conditicns 0* use, such. me an'ieal vibration also causing more or less rotation of the feed stem on its central vertical axis, so that its lateral arms 1', f2), not only space and centralize the u per ,part of the fed stem F, as before Stat "but also act, to flfi iil 'n 6X- tent, as agitators to insure the descent of the lubricant within the container.

The structure of feed stem F, above described is simple, cheap and effective, requiring no tooling nor skilled labor; but it is obvious that like results may be attained by a solid stem formed with longitudinal grooves equivalent to those formed by and between the wires f, f, 7, shown. Also that the feed stem F, may be weighted by other means than the binding wrapper f It is also obvious that the coincidental snap fastenings a, 70', might be reversed as related to each other with like result: that is to say, the protuberance might be on the flange k, of the cover K, and the socket on the elastic resilient side wall a", of the container C, as illustrated in Fig. 12, so that I do not limit myself to either alternative construction of snap fastening.
